Thanks! When I apply register settings directly, I indeed get working "normal" call working. Good. Diff for illustration is below. Clearly needs some improvements. And it shows that alsa mixers are expected to be simple and obvious on D4 -- they just do not work. Current version of phone gui is at https://github.com/pavelmachek/unicsy_demo - ofono interface should be usable - AT commands need a lot more work, and they'll probably never work nicely in this design. They are just a temporary hack. (ouch, and it should be rewritten, in Vala or better Rust...)
